Hydrangea plant named ‘JPD01’

ABSTRACT

A new cultivar of Hydrangea hybrid plant named ‘JPD01’ that is characterized by its leaves that are dark in color and fade to dark red in autumn, becoming more black in color in acidic soil and more red in color in neutral soil, its blooms on terminal, lateral and basal buds with a period of flowering that begins in mid-June, its lacecap inflorescences that are pink-red in color turning dark red in color in autumn until frost, its dried flowers that stay dark red in color in a vase for more than a year, its compact plant habit that is well-branched with rigid stems, and its good cold hardiness and is not affected by the frost in spring as it blooms on basal and lateral buds.

Botanical classification: Hydrangea macrophylla x Hydrangea serrata.

Varietal denomination: ‘JPD01’.

CROSS REFERENCE TO A RELATED APPLICATIONS

This application is related to a European plant breeders' rights application filed on Jan. 28, 2019, application No. 2019/0264 and a Canadian plant breeders' rights application filed Jun. 29, 2020 application No. 20-10276. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea macrophylla x Hydrangea serrata named ‘JPD01’ and will be referred to hereafter by its cultivar name, ‘JPD01’. ‘JPD01’ represents a new Hydrangea, a perennial shrub grown for landscape use and as a potted plant.

‘JPD01’ was derived from an ongoing controlled breeding program directed by the Inventor. An objective of the breeding program included developing a new cultivar of Hydrangea with dark leaves, attractive fall foliage and flower colors that is free flowering and hardy.

‘JPD01’ arose from a controlled cross made by the Inventor in Angers, France in June of 2013 between Hydrangea ‘Julisa’ (not patented) as the female parent and Hydrangea ‘MAK20’ (U.S. Plant Pat. No. 24,820) as the male parent. ‘JPD01’ was selected as a single unique plant from amongst the resulting seedlings in May of 2014 in Sainte Gemmes sur Loire, France.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventor in July of 2014 in Sainte Gemmes sur Loire, France. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘JPD01’ as a unique cultivar of Hydrangea.

-   -   1. ‘JPD01’ exhibits leaves that are dark in color and fade to         dark red in autumn, leaves become more black in color in acidic         soil and more red in color in neutral soil.     -   2. ‘JPD01’ exhibits blooms on terminal, lateral and basal buds         with a period of flowering that begins in mid-June.     -   3. ‘JPD01’ exhibits lacecap inflorescences that are pink-red in         color turning dark red in color in autumn until frost.     -   4. ‘JPD01’ exhibits dried flowers that stay dark red in color in         a vase for more than a year.     -   5. ‘JPD01’ exhibits a compact plant habit that is well-branched         with rigid stems.     -   6. ‘JPD01’ exhibits good cold hardiness and is not affected by         the frost in spring as it blooms on basal and lateral buds.

‘Julisa’, the female parent of ‘JPD01’, differs from ‘JPD01’ in having mophead type inflorescences that are blood red in color when blooms are opening. ‘MAK20’, the male parent, differs from ‘JPD01’ in having stems that are less rigid and yellow-green in color with dark lenticels; the stems of ‘JPD01’ are green and tinged with red in late summer and fall. ‘JPD01’ can be most closely compared to the Hydrangea macrophylla cultivar ‘Dark Angel’ (not patented) and Hydrangea serrata ‘Spreading Beauty’ (not patented). ‘Dark Angel’ is similar to ‘JPD01’ in having dark foliage and flowers that are red-pink in color. ‘Dark Angel’ differs from ‘JPD01’ in having leaves that are lighter in color with veins that are more green and inflorescences that are lighter in color and a different form. ‘Spreading Beauty’ is similar to ‘JPD01’ in having sepals that are similar in shape. ‘Spreading Beauty’ differs from ‘JPD01’ in having leaves that are lighter in color, flowers that are lighter red in color and a less upright plant habit.
